Medium Voltage Drive

3.3-11kV

250-6000KW

The medium-voltage drives manufactured by this company use Cascaded H-Bridge Multilevel Inverter technology. These drives are composed of multiple low-voltage power cells connected in series.

These drives are built using low-voltage IGBTs, achieving an efficiency of over 98%. The power factor of these drives exceeds 96% without the need for a power factor correction capacitor.

These drives, compliant with IEEE519_1992 requirements, generate harmonics of less than 5%, and the input current waveform is nearly sinusoidal. Due to the multilevel nature of the output voltage waveform, the motor output current is sinusoidal, allowing installation on standard motors and cables used in the system.

Other features of these drives include modularity, meaning all power cells are identical and easily replaceable. Additionally, all power cells are isolated from the control section via optical cables, and their control and command signals are transmitted in a modulated form through two optical fiber lines.

Performance	Specifications
System Protections	Overload Capacity	120% of rated current: 2 minutes 150% of rated current: instantaneous trip
	Transformer Protections	Transformer overcurrent, alarm and trip for each of the three transformer windings, and surge voltage protection.
	Independent Power Cell Protections	Overheating of power cell heat sinks, undervoltage protection, overvoltage protection (above 1170 V), input phase loss protection, short-circuit protection with fast-blow fuses, optical cable disconnection protection, and bypass protection (optional).
	Inverter Protections	Overcurrent, inverter overvoltage, overheating of power cell cabinet, control power phase loss protection, short-circuit protection of control power supply, cabinet door lock, overcurrent, short-circuit, and overtemperature protection of cooling fan motors, ground fault protection (optional), HMI signal disconnection, serial communication network fault, central control board fault, and speed signal or feedback loss.
	Automatic Control Protections	Overcurrent control protection during acceleration, which prevents excessive speed increase and manages motor ramp-up time, and overvoltage control protection during rapid deceleration, which prevents excessive speed drop—these two protections are referred to as Stall Prevention.

	Medium Voltage Main Switch Control	The drive’s readiness conditions for closing the upstream disconnector or for its forced opening are controlled via the output relay.
	Bypass Switch	Capability to bypass the power cell (optional).
Software Control Functions	Panel Display	• Capability to display and adjust system parameters and functions • Error log recording up to 256 MB or more using an SD card • Display of system alarms and faults as Heavy or Light Faults • Ability to identify the type of fault and the location of each defective power cell independently • Display of control status and trends with a resolution of 1024 × 600 pixels • Parameter storage with Upload and Download capability, and access control via password
	Function for Identifying Motor Parameters	This function is used to identify motor parameters when operating in vector control mode. It should be noted that the motor specifications must be provided to the drive prior to executing this function. The identification process is then completed in two stages: static and dynamic.
	Local/Remote Control	Access to commands via the panel, near the motor, or through the DCS system can be managed through software.
	Flying or Rotating Speed Start Capability (Ability to Resume Control of a Spinning Motor)	When the motor is started (Run command), the system first detects the current rotating speed of the motor. It then continues acceleration or deceleration from that detected speed to reach the desired operating speed.
	Automatic Start	Capability of Automatic Drive Restart in Case of Unintentional Power Supply Interruption
	Jump Frequency	Capability to Set Two Separate Frequencies to Prevent the Motor from Operating at Resonance or Experiencing Severe Vibration
